INTRODUCTION
The LD OCS software (Online Control System) enables you to configure LD DSP44K or DSP45K DSP amplifiers, load current LD speaker
presets and create and manage individual custom speaker and amp presets in 80 memory slots. The software is compatible with Windows
operating systems 7, 8 and 10 and requires either a USB interface (version 2.0 or later) or an Ethernet interface for data connection.
SOFTWARE INSTALLATION
Download the file LD_OCS_Setup.exe from the product page at WWW.LD-SYSTEMS.COM and install it on a Windows PC.
ESTABLISHING CONNECTION VIA USB
Connect the USB port of the LD DSP44K or DSP45K power amplifier to the USB port of your computer using a suitable USB cable (USB 2.0,
USB-A to USB-B) and switch on the amplifier (driver installation may take a few moments. IMPORTANT: Connect NO MORE THAN 1 power
amplifier via USB). Now start the LD OCS software and click on the magnifying glass icon with the plus symbol under Devices (Fig. 1). The
connected amplifier will be displayed with model number, name and serial number under Amplifiers (Fig. 2). You can now synchronize the
amplifier’s current settings with the software by double-clicking on the power amplifier model (Fig.3).
12 3
DISCLAIMER
In the event of operator error, improper use or negligent handling of the software, the manufacturer (Adam Hall GmbH does not accept any
liability for any damage to equipment of any kind or any software; personal injury included.

ESTABLISHING CONNECTION VIA ETHERNET
Connect the Ethernet port of the LD DSP44K or DSP45K power amplifier to your computer using a suitable Ethernet cable and turn on the
power amplifier. If you want to directly connect and manage 2 or more LD DSP44K or DSP45K amplifiers directly via a PC, please use an
Ethernet switch and configure a separate IP address for each power amplifier (e.g. 192.168.0.100, 192.168.0.101, etc.). The amplifier’s
IP address can be configured manually on the device itself or with the OCS software under Ethernet Config. The IP address of the LD
DSP44K or DSP45K amplifier is set at the factory to 192.168.0.100. This means that a different IP address must be used in the system
settings of the PC under Internet Protocol Properties Version 4 (TCP/IPv4), in this case, for example 192.168.0.1 (Fig. 4). IP settings
can be assigned automatically (Fig. 5), if the network supports this function (e.g. network router). Start the OCS software and in this case,
ensure that DHCP is enabled under Ethernet Config (DHCP enabled, Fig. 6). If necessary, check Use DHCP and click on the button Update
IP/DHCP. Furthermore, in the Ethernet Config window, the device search function can be de-activated (Search Devices), the IP address
of a power amplifier can be edited (if DHCP is not being used, enter the numbers in the input field and click Update IP/DHCP), the Ethernet
module of the power amplifier can be reset (Reset Ethernet Module) and the power amplifier can be assigned a name (enter name into
the field under "Device Name" and click Change Device Name ). To identify a power amplifier, click on the desired power amplifier in the
device list, then click Identify Device. The power amplifier’s name and its IP address will be displayed briefly in the device display.

Close the Ethernet Config window and click on the magnifying glass icon with the plus sign under Devices (Fig. 1).
The connected amplifier will be displayed with model number, name and serial number under Amplifiers (Fig. 2). You can now synchronize
the entire library in the data memory with the software by double-clicking on the power amplifier model (Fig.3).

Project - Preferences – click on the button Preferences to enter general settings such as relative humidity and ambient temperature (for
delay calculation), to define minimum and maximum values in the Frequency Response window, to activate unwrapped phase range and
to switch the phase threshold from Auto to Full Band and vice versa. Clicking Restore defaults values will restore these to factory settings
when the software is next started.

limit range. Brief illumination is not critical. To protect the system, any excessive signal level is lowered
smoothly by the integrated limiter. If the CLIP indicator remains lit for longer or permanently, reduce the
volume level.
PMS – the PMS (Power Management System) is an electronic protection system which constantly monitors and
regulates the main power amplifier parameters (signal input, load, temperature, current) in order to draw
only the required current from the power supply for safe operation. The PMS display illuminates in the
following situations:
1 If, due to unfavourable working conditions, the internal temperature increases and approaches the
threshold level at which the automatic switch off function will be activated to avoid overheating of the
system. In this case the system takes control and reduces the power to a level at which the power stage
is not switched off.
2 In the event of excessive power consumption. This situation occurs exclusively under laboratory
conditions in long-term tests with sinusoidal audio signals and dummy loads or in ongoing acoustic
feedback conditions. Here, the PMS system intervenes to avoid damage to the speakers and to prevent
triggering of the main circuit breaker or blowing of the electrical fuses.
OUTPUT LEVEL – level display of output channels A to D.
TEMPERATURE – displays the operating temperature of output stages A to D.
36 Frequency response – graphical representation of frequency response.

LD SPEAKER PRESET LIBRARY
Download the desired LD Systems speaker library from the product page (LDDSP44K / LDDSP45K) at WWW.LD-SYSTEMS.COM, save it in
the memory of the PC in a folder of your choice and unzip it if necessary. Start the OCS software and establish a connection to the power
amplifier (USB / Ethernet). Click on “LIBRARY” in the overview window, then on “LD Speaker Preset" and open the previously downloaded
LD Systems speaker library by clicking on the button "Open LD Speaker Library from disk”. Select the file on the PC and click on "Open".
The loudspeaker presets will now be displayed with names in the list of speaker presets. Transfer the LD speaker library to the amplifier by
clicking on the button "Send LD Speaker Library to amplifier". The presets are now available for use and can be loaded via the selection
window of channels CH A to CH D (see point 34). Right-click the desired preset to save it individually as a file on the PC (save to disk).
CREATING AND MANAGING CUSTOM SPEAKER PRESET
The OCS software enables you to create and manage individual speaker presets (custom speaker presets) for the LD systems DSP power
amplifiers DSP44K and DSP45K. Log in to the OCS software as an administrator by clicking the Mode button in the menu bar. Enter the
password "admin" and confirm with OK. The EDIT button will now be displayed in the SPEAKER PRESET (No. 34) editing field. Click EDITto
open the editing field for the custom speaker presets and to view the editing options. First of all, configure the OUTPUT ROUTING (single,
2-way, bridge) when creating a speaker preset.
Single – each channel is individually adjustable via CHANNEL EDIT and SPEAKER PRESET EDIT and can be controlled by any signal source (SOURCE).

2-way – channels CH A and CH B or CH C and CH D are configured as a 2-Way system. Channels CH A to CH D can be set up individually and signal
control for a 2-way system is achieved via the same signal source. Only channel CH1 or CH 3 is available for editing in the CHANNEL EDIT window.
Bridge – the power amplifiers of channels CH A and CH B or CH C and CH D are connected to create a more powerful amplifier. Input channel CH
1 and output channel CH A (or CH 3 and CH C) are available for editing. The signal is controlled via CH 1 or CH 3. Please note the pin assignment of

CREATING AND MANAGING AN AMP PRESET
An amp preset consists of the selection of speaker presets from the libraries (Library) "Custom Speaker Preset" and "LD Speaker Preset”
and the configuration options in the field CHANNEL EDIT (point 32). Select the desired speaker presets for the channels CH A to CH D (point
34) and adjust the gain, polarity, mute, delay and equalizer depending on the application and the listening habits as required in real time.
An amp preset created in this way can be loaded directly into the memory of the power amplifier (see point 29 AMP PRESET – SEND), and
saved as a file in the memory of the PC. In both cases, select an empty preset (empty) in the operator panel AMP PRESET (item 29) using the
arrow symbols and enter a name for the preset in the display or input field. To load the amp preset into the power amplifier, click on SEND
(send amp preset to amplifier library). To save it up as a file on the PC, click on the disk symbol (Save an Amp Preset File to disk), select a
location on your PC and save it.
